We’ve facing here a very strange situation with sipgate in germany.
When we make outbound calls, we have no incoming audio, but ougoing.
When someone calls us from outside (inbound call) audio works in both directions.
Event the support of sigate couldn’t help us.
It seems not to be a firewall or nat related issue because, we have an other trunk running on the same freepbx without any problems.
Tried all possible diffrent trunk configuration without any success yet.
Good point - I have the same problem when I try to call my own PBX from my PBX (dial the office line from my desk phone) and I don’t think I’ve ever figured out a better way to do that than to use a different outbound route when calling my own external number.
I use the same outbound for cell phones because of this problem.
I don’t think that’s what you’re seeing, but it reminds me a little bit of what it sounds like you’re seeing.
It’s possible that you’re internal address is leaking out through your NAT. Make sure all of your NAT settings are correct in the trunk, the outbound route, the extensions, etc.
I guess I might just have to try that. Nothing else I’ve tried in the past 10 years has worked, so that might knock it down.
Actually, I think the “easiest” solution is to do it the way I’ve done it. I have to have the second route anyway (for my cell phone/local prison phone customers) but I’ll look at the loopback route thing and let everyone know.
I’ve tried so many things trying to get this to work that I just don’t remember what didn’t work. It’s been a problem for me since Asterisk 1.4…
